Abstract

Powder composites composed of a nanocrystalline ZrO2 + 3 mol.% Y2O3 and 20 wt.% Ni, Cr, and Ta are prepared by a high-pressure compaction technique. In compacted composite powders, the mechanisms of densification are shown to be controlled by plastic deformation or degradation of metallic particles. The presence of a metallic component does not affect the growth rate of monoclinic phase under the stress-induced TM transformation conditions leading to the increased content of M-phase.
